This presentation provides a comprehensive overview of problem-solving methodologies, focusing on algorithms, program design, and the use of flowcharts. It begins by defining algorithms and their role in program development, followed by an exploration of the program design process, including problem-solving and implementation phases. The lecture introduces pseudocode and structure diagrams as tools for algorithm representation, alongside detailed explanations of flowcharting symbols and conventions. It covers structured programming concepts, including selection and loop structures, with examples to illustrate their application. The presentation concludes with a summary of modular design principles and highlights the advantages of each method discussed. This resource is designed to aid students in understanding and applying these fundamental concepts in artificial intelligence and computer science. Desklib provides past papers and solved assignments for students to enhance their learning.
